Large ISP migrations become difficult when teams try to handle the entire subscriber base in one massive project. Cgates and PortaOne kept the migration moving by splitting the subscriber base into smaller, manageable migration groups instead of trying to solve every edge case upfront.
This phased approach reduced operational pressure and allowed the team to migrate customers step by step, starting with simpler cases and leaving more complex scenarios for later.
The result: a controlled migration process where complexity was handled gradually, not all at once. Learn more about Cgates’ billing migration journey: https://www.portaone.com/case-studies/billing-migration/
